Installing and Cabling Enclosures

Testing the Enclosure Connections
Use this procedure to power on the newly installed system.
1. Press the power switches at the back of each drive enclosure to the On (
–)
position.
This ensures that the disks in the drive enclosures have enough time to completely
spin up before being scanned by the RAID modules in the controller enclosure.
Depending on your configuration, it can take several minutes for the system to
power up.
While enclosures power up, their LEDs blink. After the LEDs stop blinking, if no
LEDs on the front and back of the enclosure are yellow, the power-on sequence is
complete and no faults have been detected.
For a description of LED behavior and status, see “Hardware Components and
LEDs” on page 11.
2. Press the power switches at the back of the controller enclosure to the On position.
If the enclosure’s power-on sequence succeeds as described in Step 1, the system is
ready to use.
Correcting Enclosure IDs
When installing a system with drive enclosures attached, the enclosure IDs might
not agree with the physical cabling order. This is because the controller might have
been previously attached to some of the same enclosures and it attempts to preserve
the previous enclosure IDs if possible. To correct this condition, make sure that both
controllers are up and perform a rescan using RAIDar or the CLI. This will reorder
the enclosures, but can take up to two minutes for the enclosure IDs to be corrected.
To perform a rescan using the CLI, type the following command:
rescan
To rescan using RAIDar:
1. Select Manage > General Config > Enclosure Management > Reorder Enclosure
IDs.
2. In the Reorder Enclosure IDs panel, click Rescan.
